Fixing the Date Issue in Morris.js Graphs: A Simple Guide

The Morris.js library is a popular choice for creating easy and beautiful graphs in JavaScript. However, many developers encounter a problem when trying to format dates on the x-axis. Specifically, some see an unexpected 19 added before their month-day date, leading to a confused interpretation of the displayed dates. In this guide, we will explore the steps to resolve this issue and ensure your date format is presented correctly on your graph.

Understanding the Problem

When fetching date data from a MySQL database, it’s common to format it in a way that’s user-friendly. However, if the dates are formatted incorrectly or parsed poorly in JavaScript, it can lead to the wrong year being displayed in your graphs. For instance, displaying a date as 11-05 could lead to incorrect parsing as May, 1911, which can confuse viewers and misrepresent the data. This happens due to JavaScript's handling of date strings when they don’t contain year information.

Solution Overview

The key to resolving this date issue lies in how you handle date formatting in both PHP and JavaScript. Let's break down the solution step-by-step to ensure clarity.

Step 1: Adjust PHP date formatting

Start by ensuring you retrieve the full date from your database and format it properly. In the SQL query you might have something like this:

By using $row['Date'] directly, you retain the original date formatting which will help in proper JavaScript parsing.

Step 2: Update the Morris.js graph configuration

Next, modify the JavaScript code where you create your Morris.js Line graph. The xLabelFormat function is critical here, as it formats the date correctly for display in your graph:

Step 3: Full example for clarity

Putting it all together, here’s a complete example of an HTML page that demonstrates setting up a Morris.js graph with correctly formatted dates:

Conclusion

By carefully managing how you retrieve and format dates in your Morris.js chart setup, you can eliminate the confusion caused by unexpected year formatting. Stick to full date formatting in your data retrieval (from PHP) and leverage JavaScript to handle the presentation accurately. Now, you can create graphs that clearly and accurately represent your data without any confusing formats.

Implement this simple fix, and you'll have visually appealing graphs that communicate the correct date information effectively!
